UNITED STATES CHARLES DONAT RICHARD, of NEW YORK, N. Y.

MILEAGE-REGISTER.

Application filed June 28, 1916.

To all whom it may concern:

Be it known that I, Crnmnns D. RICHARD, a citizen of the Republic of France, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Mileage-Registers, of which the following is a specificatlon.

This invention relates to mileage registers, and has particular reference to a novel and practical improvement in the devices of the type referred to which are particularly designed to be carried by the hub of a vehicle vvl'hcelel to register the number of miles trave e A primary object of the invention is to provide a mileage register having novel means for driving a counter or register of the rotary type. Although devices of this character have been heretofore used, the same have not given the most satisfactory results on account of the fact that the relatively frail and diminutive mechanism necessary for driving the counter is easily put out of order by the severe strains and shocks caused by the vibrations and movements of the wheel and axle. Accordingly, the present invention proposes to provide a mechanism that, although of a relatively diminutive character is substantial, reliable, and accurate in its operation, and protected in the best possible manner from the damaging effects of the wheel and axle movements referred to.

A further object of the invention is to provide a construction which will keep oil or axle grease from entering the counter or register compartment. Heretofore considerable difiiculty has been experienced in successfully accomplishing this result, although various expedients have been utilized, but with the construction contemplated in the present invention, this difliculty has been overcome to a maximum extent.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which- Figure 1 is a horizontal sectional view of the present invention.

Fig. 2 is a vertical sectional view thereof.

Serial No. 106,466.

Fig. 3 is a detail end elevation of the counter and its driving mechanism.

Similar references designate corresponding parts throughout the several figures of the drawings.

7 In ca rrying the present invention into effect it is proposed to utilize a substantially frusto-conical casing or shell 1, which is interiorly threaded as at 2 to fit over the hub portion H of the vehicle wheel, while the opposite end is provided with an inspection opening or window 3 for exposing to view a suitable counter or register device 4:. This counter device 4 is carried upon a supporting bracket 5 which includes a shaft 6 loosely journaled in a supporting plate or rotor 7.

This plate preferably includes a threaded coupling flange 8 for engaging with the threaded portion of the shell 1 to lock the plate and cap together, and is also provided with an abutment shoulder 9 for contacting with a flat annular seat or ledge 10 formed on the interior of the casing. The body of the plate 7 is formed at its side opposite the coupling flange 8 with a recess 11 for receiving the relatively fixed anchor disk or stator 12, which is rigidly fastened, as at 13, to the shaft 6 of the counter supporting bracket. This anchor disk is connected b means of the resilient pin element 1 1 with the nut 15 on the axle A of the vehicle, and thus, the rotary counter i is held in a stationary position in the counter chamber 0, since it is connected or coupled with the stationary nut 15 on the axle.

With further reference to the attaching plate or rotor 7, it will be observed that the same is so constructed to prevent the working of oil and grease from the axle housing chamber B of the shell 1 into the counter chamber 0. That is to say, the side wall of the recess 11 is provided with an annular packing receiving groove 16 for receiving a suitable fiber packing, while the side wall of the recessed central portion 17 of the anchor disk or stator 12 is also provided with a groove 18 for holding a fiber washer. This recess 17 of the anchor disk snugly receives the collar 19 of the plate 7 which surrounds a central packing cavity 20. This packing cavity is adapted to receive a suitable fiber or equivalent washer 21, which may be held in place by a threaded steel bushing ring 22, thus compressing the packing and affording the greatest resistance possible to the entrance of lubricant into the counter chamber C by way of the shaft 6. Owing to the tight fit of the shoulder 9 of the attaching plate 7 with the seat 10 of the shell, no oil can pass from the chamber to the chamber U at this point, and with the arrangement of packings above described, oil and grease are effectually prevented from reaching the counter along the shaft 6.

It will therefore be apparent that the rotor element 7 and stator element 12 provide in eileet an oil-proof partition. That is tosay, owing to the formation of the rotor 7, which permits of the nesting of the stator 12 therein, and the numerous packing rings interposed in the joint between the two, an oil proof partition is provided which effectively prevents oil and grease from the axle A entering the register chamber or compartment C.

As will be observed from Figs. 1 and 2 of the drawings, the attaching plate 7 rigidly carries on the face thereof, that opens into the counter compartment, a driving pinion 23. This pinion is adapted to actuate the counter device 4:, and to this end there is employed a pinion 2%: which meshes with the pinion 28, and is mounted on one end of a worm shaft 25, having thereon a worm 26 which in turn meshes with a worm pinion 27 fastened on a counter actuating shaft -18. This counter actuating shaft is journaled in the offset arms 29 of the bracket 5 which supports the counter l, and extends longitudinally oi? the counter, as shown in Fig. l. The of shaft 28 opposite the pinion 27 is provided with a crank disk 30 having thereon an eceentrically mounted crank pin 81 on which is loosely mounted a pawl 32, while on the opposite side of the disk 30, on the shaft 28, is loosely mounted a check pawl 33, the free end of which, as shown in Fig. 2, engages the ratchet wheel 84 on thecounter operating shaft 35 in such a way as to prevent the turning of the latter backward. The said pawls 32 and are connected by a spring whereby both oi the same will at times engage the toothed periphery oi the ratchet wheel With this arrangement, it will be clear that upon the rotation of the hub of the vehicle and the shell 1 of the device which is carried on the hub, the attaching plate 7 u LAG 3 will also be rotated and carry with it the driving pinion 25. As the counter stands still in the counter compartment C of the casing, the rotation of the pinion 28 will drive the pinions which will in turn rotate the shaft 28 through the connections already described. The rotary movement of the shaft 28 will cause the crank pin 31, ee-

centrically mounted on the disk 80, to rise and fall, and thus cause the pawl 32 to alternately be raised and lowered, whereby in its lilting movement it will engage the teeth oi the ratchet disk to move the shaft 35 of the counter. As the paw 36 is loosely mounted on the shaft 28 and is movable about the same as an axis, the free end thereof will merely trail over the toothed periphery ot' the ratchet wheel under the influence of the spring 36, and prevent the said wheel from i'noving backward as the pawl 32 is thrust down into position to engage one of the ratchet teeth.

From the foregoing description it will be apparent that as the plate 7 is of relatively stout character and firmly held in the shell 1, the counter device is amply protected, while the resilient connection 1% between the anchor disk 21 and the nut 15 on the axle will take care or" any lateral thrusts of the axle and prevent the same from doing any damage to this part of the counter driving mechanism. Furthermore, the novel oilproof construction of the attaching plate 7 is of much practical importance, since it offectually provides for the exclusion of oil from the counter compartment C, and prevents the window 3 from being covered with oil and thus obscuring the indicia of the register.

Without further description it is thought t iat the many novel improvements of the de' vice will be readily recognized, and will, of course, be understood that changes in the arrangement and minor details of construe-- tion may be resorted to without departing from the spirit of the invention or scope of the appended claim.

I claim:

An oil-proof partition for hub-odometers including a rotor element having an external threaded portion and a stator receiving recess provided with a packing holding cavity in its side wall, and also having an internally threaded collar located in the central part of the recess, packings arranged in the said cavity and in said collar, a threaded cap for entering the collar to hold said packing in position. and a stator plate nesting in said recess of the rotor element and "formed with a socket for receiving said collar, and also having a packing holding groove in the side wall of said socket.

In testimony whereof I hereunto aliix my signature inthe presence of two witnesses.
